"Application filed J 'aniary 2'5, 1926. Serial No. 83,752.

This invention relates to' newand useful improvements in' drying ap'paratuses, andparticularly to devices for drying cloth,

- glass, or the like." i:

The present invention is an improvement on,` and is tobe `used 'in connection 'with devices shown 'in =-my -prior applications for airnozzles, Ser. No'. 73,825, filed December 7,'1925, and air pumps,` Ser.'No. '735,705,

filed-'September 3, 1924. V

The principal bbject 'of the'jp'resent invention isto 'provide a valve for controlling the flow, of air to the nozzle, with-improved means for actuating the valve into and out I; ofclosedtpositioni Another object 'is' to' provide a valve actuating means' which is simple in Construction, and 'which is. self-setting', so that a portion ofthe mechanism" will, at all times be in eXt-ended position' for' operation by the foot of'the operator, or, when mounted overhead, to be in' position for operation by a` rod or bar, infthe' hands of the operator.

Other objects landadvantages will ,be

apparent from' ?the following description when taken in connection with the accompanying drawings.

In the drawings z,

Fi ure l is a' side elevationof the 'valve mechanis m, in? association ,with the discharge nozzle( Figure 2 ,is top plan View of the 'same` the nozzle being partly in section, and the valve mechanism in .dotted lines beneath Figure 3 is an enlarged horizontal sectional View 'on the line3 -3of Figure 1.

Figure 4' is a'vertical section on the line 4-4 of Figure 3. 9 Figure 5 is a vertical section substantially on the line 5 -5 of Figure 4.

Referring particularly to the accompany-.

ing drawings, 10 represents the' floor of a room, car, automobila, or the like, and -disposed above the flooris an elongated casing llghavingits outer portion formed with an elongated recess 12, in the bottom and side walls of which are formed the perforations 13, for escape of air onto the object to be dried. Connected to the rear of the nozzle are the pipes 14:, said pipes extending down wardly through the floor and being connected with the opposite ends of the head of the T-connection 15. To the outer end of the leg of the T-connection 15 is a pipe 16 which leads to a suitable source of compressed air, such as the air pump in my previously mentioned application. Formed within the said connection is a valve seat 17, and engaged on' the seat is the valvelS, said valve being provided with a'stem 19'extending through the stuiflng box 20, and formed with the spiral rib or' screw thread '21. Mounted beneath the floor are the depend ing parallelguides 22, in which are s'lidably arranged the vertically reciprocable rack bars 23, said bars extending upwardly through the' floor and being provided with the heads 24 for engagement by thefifot of the operator. Threaded onto the'outer end of the stem of the valve, and meshing with both of said rack bars, is a gear'25,th'e end I of the stem beyond said gear 'being 'a-ngular in cross section and fitted 'within-a cor responding opening in a housing 26', which is connected to and bridges the said guides I 22. i

It will be `understood that the' pipe 16 may be connected to a suitable tank containing compressed air, if desired, instead hof 30 being connected with the pump, previou sly mentioned, without departing from the spirit of the present invention.

From the foregoing it will be seen that When the operator places his foot on the elevated rack bar 23, and depresses same, said bar will cause the gear to rotate, and because said gear is held against lateral movement by housing 26, it will drive the threaded portion 'of the stem ther'ethrough, wththe result that the valve will be'properly seated against the seat 17. *At the same time, the gear, by reason of its meshing engagement with the other, or formerly de'- pressed rack bar, will cause 'said second bar to be elevated into position to be depressed. The depression of this second bar cause's the rotation of the gear in the opposite direction, and the valve to be moved from its seat. Thus means for operating'the valve into or' out of seated position, will always stand in elevated position ready' for'depression by the foot of the operator.

In some nstances this valve may be located overhead, and out of reach of the foot. In such a case the operator can readily move the rack bars by means of a rod or bar pressed against the outer ends of the rack ars.

What is claimed is:

l. The combination with a Conduit and a valve therefor having a longtudinally movable stem,-of &wall lying approx-imately par allel with said Conduit, a .rotatab'le 'actuat'or for imparting longitudinal movement to said valve tem, and rectilinee ly movble op- 6 erating members for imparting"motion to said actuator, said Operating members e::.- tending through said wall. i
